In addition, in clock and watch 1, since the cylindrical portion 352 of date wheel pressing piece 35 is arranged on wheel shaft 741 and twenty-four theory Between the wheel shaft 451 of hour wheel 45, therefore the case where capable of being in contact to wheel shaft 741 with wheel shaft 451, inhibits, so as to Enough the case where rotating to wheel shaft 451 with the rotation of wheel shaft 741, inhibit.It is further possible to wheel shaft 451 because of quilt Be injected into wheel between centers oil and as the case where rotation of wheel shaft 741 is rotated, is inhibited.
In this way, according to clock and watch 1, the case where capable of being rotated to each needle pivot with the rotation of other needle pivots Inhibited.
In clock and watch 1, due to being arranged on the wheel shaft 741 of hour hands wheel body 74 and the wheel shaft 451 of twenty-four theory hour wheel 45 Between guide portion be made of the cylindrical portion 352 of a part as date wheel pressing piece 35, therefore do not need to be separately provided The component of the guide portion is constituted, so as to reduce the quantity of component.
Further, since constitute the guide portion by a part of date wheel pressing piece 35, therefore can be by date wheel Pressing piece 35 is disposed in proximity at the position of hour hands wheel body 74, so as to be arranged needle stand 36 in hour hands wheel body 74 and date wheel Between pressing piece 35.According to this structure, the movement of hour wheel 70 in the axial direction can be limited by needle stand 36.
Further, since a part for the leader 321A of central tube 321 guided to hour wheel body 74 is with timely Therefore the contact site of pinwheel body gear 742 and needle stand 36, can inhibit hour wheel on same plane orthogonal to the axial direction While 70 inclination, the movement in the axial direction of hour wheel 70 is limited by needle stand 36.
In clock and watch 1, since the second wheel shaft 331 is arranged on the second wheel clamping plate 33, do not need to be separately provided pair The component that second wheel shaft 331 is fixed.Further, since central tube 321 is arranged on bottom plate 32, therefore do not need individually The component that central tube 321 is fixed is set.Thereby, it is possible to reduce the quantity of component.
In clock and watch 1, the wheel shaft 411 of fourth round 41 by train bar 34 and be arranged on the second wheel clamping plate 33 the Great wheel arbor 331 and be guided, therefore wheel shaft 411 can be guided in the not inclined situation of fourth round 41.
In clock and watch 1, due to being provided with needle stand 37 between twenty-four theory hour hand gear 452 and dial plate 12, can The movement of twenty-four theory hour wheel 45 in the axial direction is limited by needle stand 37.Further, since date wheel pressing piece 35 Cylindrical portion 352 in the leader that twenty-four theory hour wheel 45 is guided a part and twenty-four theory hour hand gear 452 and needle stand 37 contact site on same plane orthogonal to the axial direction, therefore, twenty-four theory hour wheel can inhibited While 45 inclination, the movement of twenty-four theory hour wheel 45 in the axial direction is limited by needle stand 37.
In clock and watch 1, due to by when multiple jumps position sheet body 721,722 constitute jump when locating plate 72, with by It positions the case where sheet body constitutes locating plate 72 when jumping when one jump to compare, the torque of locating plate 72, i.e. elastic force increases when can make to jump Greatly.
Here, for example, even if by positioning sheet body when a jump and locating plate 72 when constituting jump, also can by increase this one The thickness of sheet body is positioned when a jump and increases the elastic force.But when thickness is relative to the wink for positioning sheet body when jumping When the ratio of the width dimensions in jump portion becomes larger, it is difficult to sheet body is positioned when forming jump by punch process, thus in the presence of that can not hold Change places when producing jump position sheet body the case where.In contrast, according to clock and watch 1, locating plate when due to not needing to increase each jump The thickness of body 721,722, therefore sheet body 721,722 can be positioned when forming each jump using punch process, so as to Locating plate 72 when being enough easily manufactured by jump.
Although in addition, for example institute can be increased and the flat shape of positioning sheet body is changed when to one jump Elastic force is stated, but in this case, due to being applied to the power on per unit area relative to positioning minute wheel 73 when jumping and becoming larger, Therefore wear resistance is reduced, positions sheet body when furthermore, it is desirable to redesign jump.In contrast, according to clock and watch 1, due to opposite The positioning minute wheel 73 when jumping and to be applied to the power on per unit area constant, therefore wear resistance is able to maintain that, further, since not Need to change the shape that sheet body 721,722 is positioned when each jump, therefore, the design of locating plate 72 is wanted when can shorten jump Time.
In this way, according to clock and watch 1, the torque of locating plate 72 when can easily increase jump, therefore can increase by hour wheel The type for the mechanism that body 74 is driven, so as to which diverse clock and watch are easily manufactured.
In clock and watch 1, positioning sheet body 721,722 is identical on flat shape, size, thickness from each other when jump. It therefore, there is no need to position sheet body when manufacturing the jump of multiple types, to simplify the management of manufacturing process or component.
The gear teeth 731 when the stop position of hour hands wheel body 74 when the time difference is corrected is by being arranged at jump on positioning minute wheel 73 And it is determined.Therefore, minute wheel 73 is positioned when jump to be fixed on hour hands wheel body 74, and position minute wheel when hour hands wheel body 74 and jump 73 integrally rotate, to for example be fixed with positioning minute wheel 73 when locating plate 72 is fixed on hour hands wheel body 74 and jumps when jumping The case where comparing, capable of being deviated to the stop position of hour wheel body 74 in the situation on hour hand gear 71 inhibits.As a result, can Enough reduce the offset of the indicating positions of the hour hands 23 when time difference amendment.
In clock and watch 1, since locating plate phosphor bodies portion 721A, 722A lead to respectively when the jump of positioning sheet body 721,722 when jumping It crosses the arc sections 712 being arranged on hour hand gear 71 and is guided, therefore can definitely will be each by arc sections 712 The position alignment of sheet body 721,722 is positioned when jump, so as to fixed when positioning the positional shift of sheet body 721,722 when jumping, jumping The case where torque of bit slice 72 changes is inhibited.
According to clock and watch 1, in the case where carrying out operation to arbor 39 to make time difference amendment train rotate, when jump, is fixed Bit slice 72 is released from the engaging of positioning minute wheel 73 when jumping, and hour hands wheel body 74 is revolved in the state that hour hand gear 71 stops Turn.Therefore, can not to be installed in and hour hand gear 71 interlock twenty-four theory hour wheel 45 on twenty-four theory hour hands Indicated by 24 " when " change in the case where, to indicated by hour hands 23 " when " be modified.
According to clock and watch 1, date driving gear 81 is linkedly rotated with hour hands wheel body 74, date feed cam 83 and day Phase driving gear 81 is linkedly rotated, so that date feed bar 84 be made to be gradually curved.Also, when 83 turns of date feed cam When having moved scheduled position, by the elastic force of curved date feed bar 84, to make date feed cam 83 with bigger Power is rotated, so that the date feeding claw 82 with 83 unitary rotation of date feed cam feeds date wheel 25.Having as a result, In the clock and watch 1 of standby time difference debugging functions, instantaneously the date can be made to feed.
In addition, according to clock and watch 1, since date driving gear 81 is linkedly rotated with hour hands wheel body 74, by handle Axis 39 is operated and makes time difference amendment train rotation, and rotates hour hands wheel body 74, thus can not only be to hour hands 23 It is indicated " when " modify, additionally it is possible to while the date is modified, with implement respectively " when " amendment and the date The case where amendment, is compared, and can be improved convenience.
In clock and watch 1, the thickness of locating plate 72 is greater than the thickness of hour hand gear 71 (in this implementation when jump It is 1.5 times~2 times in mode).According to this structure, with for example jump when locating plate 72 thickness and hour hand gear 71 thickness The identical situation of size is compared, and locating plate 72 is towards the direction orthogonal with bending direction (along hour wheel 70 when being able to suppress jump Rotary shaft direction) the case where bending.That is, can inhibit to the case where locating plate 72 is distorted when jumping.By This, elasticity stable of the locating plate 72 on bending direction when can make to jump, to realize the stabilization of the torque of locating plate 72 when jump Change.
In addition, the thickness of locating plate 72 is greater than the thickness of hour hand gear 71 when by making to jump, so as to make The size of locating plate 72 and the part that positioning minute wheel 73 engages when jumping when jump (along the axial size of positioning minute wheel 73 when jumping) Greater than by hour hand gear 71 and jump when the combined thickness of locating plate 72 half.As a result, with jump when locating plate 72 and the identical situation of thickness of hour hand gear 71 compare, can excessively to when correcting the time difference when locating plate when jumping 72 and hour hand gear 71 tilt the case where inhibited.
In clock and watch 1, the date drive gear 81 via intermediate train (amendment wheel 51 and second date setting wheel 52) and with Hour hands wheel body 74 is linkedly rotated.According to this structure, due to directly being engaged with hour hands wheel body 74 and date driving gear 81 The case where compare, the site of engagement of gear is more, therefore when being applied with the power formed by impact to machine core 2, can be easy Ground discharges the power.Thereby, it is possible to because of the power to making hour hands wheel body 74 or date that the position of gear 81 be driven to shift Situation is inhibited.Furthermore it is possible to the direction of rotation of opposite with the direction of rotation of hour hands wheel body 74 date driving gear 81, Date driving gear 81 is adjusted relative to the position of hour hands wheel body 74.
In clock and watch 1, amendment wheel 51 is used for time difference amendment train, also, is also used in date feed mechanism 50 Between in train.That is, a gear of time difference amendment train and a gear of intermediate train are shared gear.Accordingly, with make The case where gear of intermediate train is all separately provided with the gear of time difference amendment train is compared, and the quantity of gear can be reduced, And then the quantity of component can be cut down.In addition, the quantity of shared gear may be two or more.
In clock and watch 1, hour wheel 70 is arranged at the surface side of bottom plate 32, amendment the 51, second date setting wheel 52 of wheel with And date feeding portion 80 is arranged at the surface side of calendar plate 31.That is, the axial position of hour wheel 70 passes through bottom plate 32 And positioned, the position in the axial direction in amendment the 51, second date setting wheel 52 of wheel and date feeding portion 80 passes through calendar plate 31 And it is positioned.
According to this structure, also same with hour wheel 70 as amendment the 51, second date setting wheel 52 of wheel and date feeding portion 80 The situation that ground is arranged in the surface side of bottom plate 32 is compared, can easily make amendment wheel the 51, second date setting wheel 52 with And the aligned in position in the axial direction in date feeding portion 80, inhibit so as to the deviation to the position in axial direction.
Further, since it is same that amendment the 51, second date setting wheel 52 of wheel and date driving gear 81 can be made to be located substantially at In plane, therefore even if exerting a force in time difference amendment to each wheel, the case where each wheel run-off the straight, can also be inhibited. Therefore, even if passing through the torque for increasing locating plate 72 when jumping, and make required in order to rotate hour hands wheel body 74 when correcting the time difference The power wanted becomes larger, so that the power applied to each wheel becomes larger, can also be appropriately carried out time difference amendment.
